Abstract
For a collection
of subsets of a setS, letn k be the maximal number of sets from
such that no point ofS belongs to more thank of them. Then the limitδ of the sequencen k /k is related to the valuev of the game in which the minimizer selects a setα in
, the maximizer a pointx inS, and the payoff isϰ α (x), byδ≤v −1≤inf v δ v . Herev is any finite subset ofS and δ v the corresponding limit. Analogous results hold for covering.
The bounds obtained in this way forn k and in particularn 1 reflect the influence of the boundary ofS when, for instance,S is a convex body to be packed with congruent copies of another body. In some cases, the bounds are sharp.
